Celtic enter at the second qualifying stage – meaning three knock-out ties before the group stages and face former player Erik Sviatchenko and FC Midtjylland from Denmark.
The winners already know they’ll play either PSV Eindhoven or Galatasaray in the next round – the same stage as Scottish champions Rangers enter.
However it’s all about Ange Postecoglou's first competitive match in charge and 9000 fans will be inside Parkhead to cheer the team on – the largest at the stadium since March 2020.
Here’s what you need to know ahead of the game...
Who: Celtic v FC Midtjylland
What: UEFA Champions League qualifying, round two
Where: Celtic Park, Glasgow
When: 7.45pm, Tuesday July 20, 2021
How to watch
For anyone not in the 9000-strong crowd, the match will be shown on Celtic’s live streaming service CelticTV for season ticket holders, via the Pass to Paradise service. The match is also live on subscription channel Premier Sports and available to stream via the Premier Player.
Ange Postecoglou had some pre-season concerns over Vasilis Barkas, Mikey Johnston, Karamoko Dembele and Ismaila Soro during the 0-0 draw against Bristol City but the goalkeeper is back, and he will have Leigh Griffiths back in contention for a place in the squad for the European clash following his early exit from Celtic’s pre-season camp in Wales. However, it’s still too early for Kyogo Furuhashi who has begun his journey to Scotland while Kris Ajer and Olivier Ntcham have been omitted from the squad.
For Midtjylland they have Erik Sviatchenko within their ranks but they will be without Aral Simsir who has tested positive for Covid.
